Hi,

New build - Fatal1ty X370 Professional Gaming. It doesn't POST. Instead, the mobo glows blue for ~10 seconds, then gives 5 quick red flashes, then goes to a red slow blink.

No CPU/chassis fan power - all I see are the glowing mobo lights. Power switches (chassis or mobo) do nothing.

I've checked all power connections, checked/relaxed the cpu tension, etc. No change.

Anyone know what the LED flash code means? There's nothing in the manual and googling has shown nothing.

Thanks in advance for any advice.
